Din Rail

A DIN rail is a standardized thirty five millimeter wide metal bar that has a hat-shaped cross section which is widely used for mounting circuit breakers,relays , meters etc and industrial control equipment inside equipment racks. The abbreviation "DIN" stands for DeutschesInstitutfürNormung, the German organization of standards that defines the size and shape of DIN rails. A DIN rail's length can be cut as needed by the person installing the rail and circuit breakers

The standard DIN rail used is 35mm wide. However, there are types of the rail having lesser widths such as 15mm or 7.5 mm.

The European Standard EN 50022 and the IEC standard 60715 specify the DIN rail for mounting low voltage switchgear and control gear.
